    While all these numbers of potential waste from turbine blades sound bad, realize that the CUMULATIVE projected waste from ALL turbines decommissioned between now and 2050 is less than 5 percent of the coal ash the world produces EACH YEAR. So yes, this will be good for PR, and maybe it will even save a little money, but recycling turbine blades is of miniscule importance compared to reducing carbon emissions and reliance on fossil fuels overall.

      @@VeniceInventors In principle, yes, but in fact, only about 60% gets reused, meaning about 200 times more coal ash than turbine blades would have to be disposed of between now and 2050 assuming current levels of coal use. So every wind turbine we build is a massive reduction in the space we need to dispose of waste, even if none of the turbine blades get recycled.

    On the subject of the blades currently headed to landfill: They could easily serve a second life as a bus shelter, house roof or noise abaitment barrier at the side of a busy carriageway; it shows we have a problem with lack of creative thought rather than an item that is truely at the end of its useful life.

      Other ways to reuse the GFR, first-gen blades are materials for wall and floor tiles (which a German SMB is doing already; I'd link the video of German public broadcaster MDR directly but sadly links are not allowed. You find it under the title "Wertvolle Rohstoffe: Wie entsorgt man ein ausrangiertes Windrad richtig? | Umschau | MDR"). Researchers are already finding ways to separate the resin from the fibers of the CFR blades via acid solutions that leave the valuable tissue layers intact and allow for their recycling and of the resin. GFR and CFR fibers are also a good replacement for sand as binding and reinforcement material for concrete.

      The epoxy resin keeping the glass fibres together is indeed not very environmentally friendly and can leech for example BPA when protective layers are eroded or shredded. The reuse potential for now is mostly concrete substrate, for which there is a lot of demand. But the area where demand exists doesn't always match where the turbines are situated. So for multiple reasons it is desirable to use more environmentally friendly resins.

    Wonderful, a larger footprint per tower.
    Meanwhile, a vertical wind turbine design based on large spinnaker sails would catch more wind and be set atop one another.
    Each level of the tower should hold 3 to 6 spinnakers to increase rotation. Also, the spinnakers could be made from biodegradable or recyclable materials, such as cloth like the sails on the Cutty Sark or a Clipper ship.
    To save weight, the sails could be made in panels or with a grid of small "windows" properly reinforced in the spinnakers.
    This design in a compact version that could be mounted atop tall buildings, along the dyed to resemble a merry go round, in urban wind tunnels between buildings, and other windy places.
    The vertical layout gives options on where to place the generator, top -middle or -bottom. This will also allow extra sound proofing around the structure. The generator could be put underground.
    To minimize tower flex, a set of 4 could be loosely connected at the top by retaining bars.
    Just have a Think. If you throw away the box, so much more is possible.

    Very interesting. And very needed. I didn't hear you mention it ... but ... another major (new?) concern with these fiberglass wind turbine blades is that they do degrade while in service. They actually shed fiberglass material off the blades and into the surrounding environment. Floating ones ... into the seas/oceans ... and land based ones, which usually (around us, at least) is in farm lands. That is into the food supply. Can you say "Yikes!".
    This brings to mind the push several years ago to switch from incandescent light bulbs to compact fluorescent bulbs ... which I did ... but which, as I did hear later, contained mercury in the base and which were most probably mostly thrown into landfills as well. Can you say "Yikes!", again.
    Last item on the "balance out the good with the bad" rant; Solar panels. I love the tech ... I am a retired engineer ... I've been keeping my eyes on the progress for a long time. Initially, I had heard that it took more energy to mine & transport materials, manufacture, transport and install than the panels would ever generate in their lifetimes. Also when I looked at it a bunch of years ago the cost verses payback was absurd.
    However, time passes, progress is made. However, the one aspect that I continue to monitor is their disposal. They contain a lot of heavy metals and the vast majority of the panels reaching their end of life are ... surprise, surprise ... being dumped into the landfills. Third times the charm ... "Yikes!"
    It may sound like I'm against all these ... I am not. I'm again looking into getting my house set up with solar/batteries/inverter.
    I guess I may do what everyone else is doing ... kick that can down the street, to be delt with later by somebody else.

    Turbine blades are a pretty small fraction of the market for fiber-reinforced polymer composites. Auto, truck, and aircraft bodies, furnishings, architectural components . . . the potential is huge for a truly re-usuable polymer.
    I also wonder what, exactly, is the failure mode for blades that reach the end of their lives while still in use. If the carbon fibers are still fine, would it be possible to anneal the blades, relieving any internal stresses and healing any cracks and delaminations? (You'd need some degree of thermoplasticity in the cured polymer, but that can be designed in.)

    The 30 to 90% reduction in GHG emissions for the SECOND iteration of these turbine blades is great, but that doesn't help the primary producer unless they are still the owner and have the burden of disposal/reuse. This means NOW would be a great time to implement EPR (extended producer responsibility) for blades so that the manufacturer would see the advantage of building with a reusable material. Just like a deposit return system for bottles ensures responsibility for reuse (and fate, hopefully) of the bottle, a well conceived EPR would bake the disposal costs into initial sale, so blade with reusable material would mean a cheaper initial blade.

    This is a thrilling development in an area that has been wanting for attention. IMO, the development of alternate materials is clearly the right direction since the current generation of materials has both too short a lifetime and major limitations in recycling. PECAN15 sounds like exactly what's needed, which is not to say that further research on even better solutions isn't needed. I think this is an excellent first step and should be put to use immediately. I would really like to see more attention given to extending wind turbine lifetimes, which could further improve to the waste problem and ROI.

    Ideally, at the end of a highly stressful dynamic application on wind turbines, blades could be re-purposed to make best use of their structural properties. Perhaps architects and civil engineers could find static uses in buildings and bridges, possibly in fabric tension structures? Maybe they could alternatively be cut into standardised sizes and given a rating in a similar way to structural timber? As always, we should think about best practice in recycling; re-use, re-form, recycle.

    If a tall tree was used as the tower the blades could grafted in place before it grew to full-size. Indeed they could be harvested at different stages in their growth depending on the size of turbine you required. You could produce anything from a small bush turbine for domestic use to one the size of the mighty redwood.

    "Recyclable" is a pretty fun word and neglects things like costs, energy and emissions required to "recycle" the materials and transportation costs and energy use and emissions to get them to a facility. Then transporting those materials back to a factory where they can be reused.
    These blades are 50,000lbs each now and are mostly manufactured in China, so transportation will be huge expense and impact to the environment.
    What seems to be missed is the fact that a modern 5MW onshore turbine will generate as much energy as burning 525,000 tons of coal. So IMHO if these 75 tons of blades end up in a landfill each 25 years, so be it. And with any luck they can be ground up locally and used as aggregate in the concrete of new turbines or mixed with asphalt or concrete for local construction projects.
    But transporting blades all over hell and expelling untold amounts of energy recycling them is nuts. And all in response to BS conservative criticism as if they ever gave a rats ass about recycling. AND those same people will fight tooth and nail arguing the right for fossil fuel companies to dump toxic waste endlessly into tailings ponds, lakes, rivers, the air we breathe, etc, etc.

The resin is surely a version of plastic and will incinerate to substitute for some of the fuel required, as will any carbon fibre, and the the glass fibres will melt into the mix. You'd think the high temperatures in the furnace would incinerate adding additives in the resin. Obviously the shredder would have to be enclosed to avoid glass and / or carbon fibre dust escaping.

    such is the situation when people say "wind power is so dumb, those blades are DISPOSABLE!! dumb liberals! people inadvertantly get caught into that trap and not realize it.
    wind turbines were designed with glass fiber and other cheap, plentiful commodities and produce far, far more energy than the cost to produce those basic materials. if you take some sand and make glass fiber and take the equivelant amount of oil that you'd burn driving a half mile in an SUV (or plant based oils if you want to make it over-complicated and less efficient!), and convert that insignificant amount of resources into a wind turbine, the return on investment and overall sustainability is obvious, and that's what we need to be talking about: the details of it. They provide a good useful life and aren't super hazardous to dispose of, they break down relatively quickly and aren't reason for concern in that regard either. Again, this question, in every detail, can be addressed very easily if we talk specifics and not just vague ideas/opinions/rhetoric.
